Title: MECHANICAL SEAL DEVICE
Abstract:
Provided is a small mechanical seal device which can efficiently wash a sealing surface, and can appropriately seal a sealed fluid and a quenching liquid. In a mechanical seal device (1), two sealing surfaces, i.e., a real liquid sealing surface (131) and a quenching liquid sealing surface (132) are formed in a stationary sealing ring (130), and a quenching liquid passes through a sealing groove (133) provided between the sealing surfaces. A quenching hole (134) which penetrates through the stationary sealing ring (130) in the axial direction is formed in the stationary sealing ring (130). The quenching liquid passes between an intermediate chamber (C) provided on the back side of the stationary sealing ring (130) and the sealing groove (133) via the quenching hole (134).
